HUB AND SPOIKES FOR METAL VFHEELS.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed April 27, 1914. Sergrl No. 834,598.

invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the furnish a metal hub of a construction Which may be used in connection with wheels having different numbers.sa v either 1, (3, 8 or 12.of equally spaced spoke-tastenings.

My invention is also designed to furnish a hub-and-spoke construction in which the hub-ends of the spoke are of cast metal, the

remainder of the spoke being a tube can nected with the cast hub-end by Welding. brazing or the like. 7 I

Another ob ect of this invention is to furnish a novel and useful device for rigidly supporting a brake-drum in place upon the tubular-spokes of the wheel by means oil bolts passing through the spokes, without weakening of or injury to the spokes.

To these ends my device consists of the construction and arrangement of parts here inafter described, and shown and illustrated in the accompanying drawings, in which Figure 1, is a side-elevation of my hub and spokes with a portion of the inner hubplate broken away; Fig. 2, a vertical secouter hub-flange of my wheel, provided With inwardly projecting overlapping flanges 3 threaded to take one another, as at 1, and against the outer of which flanges the inner ends of the spokes 5 abut. Centrally through the flange-plates is the usual spindle-opening 6. The annular space between the'outer rims of the flange-plates is shaped and adapted to receive between them the inner ends of the spokes of the wheel, and the sides of this space flare inwardly to 091'- respond with the correspondingly flaring sides 7 of the spoke-ends, as shown in Figs. 2 and 4. The inner, ends: of the spokes of the wheel form equal segments of a circular body conforming to the channel between the flanges of the hub-plates 12, the adjoining sides 8 of the spokes meeting on radial lines and flaringoutwardly while the inner and outer sides 7 are flared inwardly.

The inner spoke-ends, formed as above described, are formed.preferably cast, hollow. Extending between and integral with the walls of the chambered spoke-ends are webs each having. midway between the two end-walls 8, a thimble furnishing a hole 10 which extends between and through the chambers end-walls 7. Extending across each of the radial end-walls 8 is a semi-cylindrical recess 11 opposed to a corresponding recess in the adioiningend-wall 8, these recesses together forming holes 19 corresponding to and in circular alinement with the holes 10; \Vhen the spoke-ends are assembled in operative form, there is thus formed by the holes 10-12 a. circular series of equirdistant bolt-holes,-in the example illustrated in Fig. l,twentyfour in number. Through each of the flange-plates are corresponding bolt-holes 13 for bolts 14, there being a bolt-hole for each pair of neighboring spokes. The holes 13 register with an equal number of holes 10 or 12. The bolts 14: pass throughboth flange-plates and through holes 10 or 12. In the example indicated in Fig. 1, there would be six bolts 14, but it Will be seen that by reason of the twenty-four holes 1012, there may be one or two bolts l i for eachspoke or that there may be either or eight of the equally spaced bolts. Formed on the inner and outer sides of each offthe spokes is a notch 15,.t...

' es, together, forming upbn the assemspokes circularchannels or grooves which are engaged respectively by an inwardly turned lip 16 at the outer margin of each of the huhfianges i-2.

"it will now be Seen that the spokes and the hubs are rigidly held in immovable relation to each other by the inner end-abutment of the spokes, the contacting wedge-like sides the spoke-ends, the inwardly flaring sides of the spoke en'ds, the clasp of the hubflanges, the engagement of the bolts 1.4: with the hubtlangesand the spokes'and the engagement of the'lip l6 with the circularly arranged notches 15, Well by the clasp of the encircling telly at the outer ends of the spokes. I V

it is'ne'ccssarythat means be provided for securing to the rear Wheels of motor-vehicles a hraltedrum, and when, as in the present instance, the spokes'of the Wheel are formed of tubes, special'devices must be provided for securing the brakedrum in place without weakening or in uring the spoke. To

this end, the spokes of my Wheel are bored,

claim and desire to secure by Letters Patent,

1S-r7x v In a device of the described character, a spoke having an ntegral chambered metal hub-end the walls of which are connected by a Web having centrally thereof-a thimble' through which and'through the side-Walls of such chamber is a bolt-hole.

2. In a device of the described character, a spoke having a chambered metal hub-end, the end-Walls of the chamber being flared outwardly and the side-Walls being flared inwardly, and a thimble connecting, said side- Walls, there being a bolt-hole through said thimble and through said sidewalls.

3. In a device of the described character, a series of spokes having respectively a chambered metal. hub-end. the radial meeting end-Walls of. the several chambers having across their meeting faces opposed recesses gghich together form bolt-holes, the side Walls of said several chambers being connected respectively by a thimble through which and through said side-Walls is a bolthole, said sEiveral bolt-holes being equi-distant and in circular alinement.

4. In a device of the described character, a series of spokes having respectively a chambered metal hub-end, the radial meeting end-Walls of the several chambers having in their meeting' faces opposed, recesses which together formbolt-holes, the sidewalls of said chambers being connected respectively by a thimble through which and through said side-Walls is a bolt-hole, said several bolt-holes being equi-distant and in I circular alincnient, combined With a pair of hub-flanges which clamp between them said series of hub-ends, said flanges having a series of corresponding equi-distant boltholes which register With an equal number of the several bolt-holes carried by said spoke-ends.
